Is this the right type of light?

1. I assume the light is motion sensor... you have to check if it allow to be sit at such high attitude to detect motion below... but most likely the answer is yes.

2. so if 1. is yes, the next challenge is to have weather proof wiring to that location... this means thouse water proof plastic pipes and...etc. and you need to think about how to mount the light there securily..

So photo control means that it'll turn on when it senses no sunlight?

Yes, it is intended that the fixture always receive power.

Being Mercury Vapor, this fixture produces a blue-white light.

Also check out High Pressure Sodium Vapor, you will get the same illumination from a 100W fixture (more energy efficient), these fixtures produce an orange-pink light (a warmer light, but tends to make everything look beige).
